9 Claims.

My invention relates to stop means for a traveler on a ring of a spinning frame or the like.

An important object of the invention is to provide stop means of the above mentioned character adapted for use in connection with a rotating ring, to stop the traveler at a selected point and permit of the continued rotation of the ring.

A further object or" the invention is to provide stop means of the above mentioned character for use in connection with each rotating ring, so that the yarn or thread may be threaded into the traveler and united with the source of yarn in the event of breakage of the yarn without the necessity of stopping the spinning or twisting frame or the like.

A further object of the invention is to provide means to rapidly shift the travel engaging element from the path of travel of the traveler and to hold the same suitably remote from the ring to avoid contact with the balloon formed by the yarn or thread.

A further object of the invention is to provide a device of the above mentioned character which is simple in construction, cheap to manufacture, easy to operate, and which may be installed upon the ring railwithout materially altering the construction of the ring rail.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the drawings, the numeral 20 designates a vertically movable rail of a spinning or twisting frame or the like, having power driven rotating rings 2| mounted thereon, but only one ring is shown. This ring is positioned within a ball bearing raceway 22 secured within an opening 23 formed in the rail, the ring 2| having a raceway groove 24 formed thereon, and bearing balls 25 are held within the raceway and the groove 26, as shown. The ring 2| is provided at its lower end with a whirl or pulley 26, preferably formed integral therewith. This whirl is power driven by means of a belt 21. The ring 2! is provided at its top with a horizontal flange 28 and the numeral 29 designates a traveler slidably engaging the flange 28, to move with the rotating ring and also with relation thereto.

The numeral 35.) designates a spindle which is mounted upon the framework of the spinning frame beneath the rail 29. This spindle is of any well-known or conventional type and includes a whirl 3| driven by a belt 32. The rotating ring 21 is driven in the same direction with the spindle at a somewhat lower speed.

The numeral 35 designates a spool or bobbin upon which the yarn 3 1 is to be wound. This spool or bobbin is mounted upon the shaft of the spindle and is secured to the shaft for rotation therewith by any suitable means.

In the normal operation of the spinning frame or the like, equipped with the rotating ring, the rail 20 is reciprocated vertically and the ring 2| and the spindle are rotating in the same direction but the ring is traveling somewhat slower than the spindle. The traveler 29 is slidable upon the flange 28 of the ring 2 I. At the beginning of the twisting and winding operation, the diameter of the wound yarn upon the spool or bobbin is relatively small and the speed of winding is slow. Since the ring 2! is rotating in the same direction with the spool or bobbin, the traveler will have relatively slight movement with respect to the ring. As the diameter of the wind 'of the yarn or thread increases, the speed of the winding increases correspondingly and since the ring 2| is rotating at a constant speed, in the same direction with and somewhat slower than the spindle and spool, the traveler will slide around the ring in the direction of rotation of the spindle at an increased speed in proportion to the increase of diameter of the wound yarn or thread upon the spool or bobbin. However, the relative sliding movement of the traveler with respect to the ring is greatly less than the relative sliding movement of the traveler upon a stationary ring, which materially reduces friction between the traveler and the rotating ring, with the result that the pull or tension upon the yarn is properly reduced so that the tendency of the yarn to break is eliminated or reduced to the minimum. Further, by using the rotating ring, the size of the ring may be increased Without producing excessive friction between the traveler and ring.

In the operation of a spinning frame or the like having rings held stationary upon the vertically movable rail, when the yarn leading to the traveler breaks, the traveler comes to rest and the yarn may be readily threaded into the traveler and the broken yarn secured to the source of yarn. I have "found by actual tests, that when the yarn breaks, the traveler will continue to be rotated by the rotating ring, at substantially the speed of the rotating ring. This makes it difficult to thread the broken yarn into the traveler and to secure the broken yarn to the source of yarn as one hand must be employed to stop and hold the traveler. In effecting the repair of broken yarn, under these conditions, the bobbin is stopped and held by the left hand, and the right hand used to thread the broken yarn into the traveler and to secure the broken yarn to the source of yarn, as will be more fully explained. It would be practically impossible for the operator to perform the several steps, namely, the holding of the bobbin, the stopping and holding of the traveler, and the threading of the broken yarn into the traveler, while the spinning frame or the like remained in operation. As the result of this, I have provided a stop device to engage with the traveler and hold it against rotation, while the is continuing to rotate, thus eliminating stopping the operation of the spinning frame or the like. After the broken yarn has been threaded into the traveler and again secured to the source of yarn, the traveler engaging element of the stop device is shifted out of the th of travel of the traveler and held out of the path of travel of the balloon formed by the yarn.

The traveler stop device comprises a bracket which is rigidly secured to the upper face of the rail by a belt or the like and arranged near and exteriorly the rotating ring and exterior- 1y of the path of travel of the balloon formed by the yarn. The bracket 35 has a horizontal arm 36, the free end of which is bent upwardly forming a vertical cam 3'5, having a high point a shor inclined face 39 and a long inclined face 48. The horizontal arm is provided at its longitudinal edges with upstanding stops 4|, as

shown.

The numeral 32 designates a stop element which may be formed of wire or the like and includes a horizontal arm 33 having an eye or loop it formed therein, receiving a pivot element 45, extending through a large opening 45 in the arm 35. This pivot element or bolt carries a nut 41, engaging a washer 38, in turn engaging a coil spring 49. This sprin moves the bolt 45 downwardly and tends to hold it vertical but will permit of its angular movement, within limits. The horizontal arm 43 carries a vertical arm 50 at its free end, having a horizontal extension 5|, which faces outwardly with respect to the ring.

The operation of the stop device is as follows:

When the spinning frame or the like is operating under normal conditions, the stop element 42 is shifted to the outer or open position. To accomplish this, the horizontal arm 43 is swung outwardly and when it reaches the high point 33, the spring lE-l will cause the arm to quickly slide down the long inclined face 68 of the cam and engage the outer stop il. The traveler engaging extension 5i and the vertical arm are now disposed outwardly of and remote from the ring and out of the path of travel of the traveler and the balloon formed by the yarn. In the outer adjusted position, the stop device in no way interferes with the rotation of the ring and traveler. When the yarn breaks, the traveler continues to rotate with the rotating ring. In order to stop the traveler, the stop element 42 is swung inwardly toward the ring and after passing the high point 33 of the cam, will quickly snap to the innermost position for engaging the inner stop 5! The horizontal extension 5| now extends above and. radially of the iiange 28 of the rotating ring, in. the path of travel of the traveler 2S, and the traveler will be stopped when it moves into engagement with the extension 5|. It is preferable that the extension 5 be spaced slightly from the ring so that it will not contact therewith, but the extension is shiftable into the path of travel of the traveler. As soon as the traveler is brought into engagement with the extension fii, it is stopped. The operator then holds the spool or bobbin against movement with the left hand and the right hand is employed to manipulate the yarn to thread the same into the traveler. As is well-known, a portion of the yarn is passed under two of the fingers of the right hand, which are arranged to form a v and the yarn extending between the fingers is pulled up and enters the traveler. After the yarn is threaded into the traveler, and while the bobbin is still being held by the left hand, the holding element s2 is swung to the outer position by the right hand and as soon as the element 32 passes the high point 38 it will snap to the complete outer position. The free end of the broken yarn is held in the left hand holding the bobbin or in the mouth, and immediately after the outward movement of the stop element, the bobbin is released by the left hand and the free end of the broken yarn is grasped by the right hand and secured to the source of yarn and the twisting and windin operation is continued.

In Figures 9 to 14 inclusive, I have shown a modification of the stop device, for use with the traveler 2d and rotating ring 2!. In this modification, the numeral 52 designates a vertical bracket which is secured to the rail 26 outwardly of the rotating ring 2| by a bolt or screw 53. The bracket 52 has a horizontal arm 54, upon which a horizontal bearing sleeve 55 is rigidly mounted. This bearing sleeve has a cylindrical bore 56 and a longitudinal radial groove 51 leading into the bore. At its inner end, the sleeve 55 has a recess 55, provided with a vertical shoulder 58 and a horizontal shoulder 59.

The numeral 5% designates a traveler stop element including a cylindrical horizontal arm 53, slidably mounted within the bore 55. This horizontal arm is provided with a radial pin 60, adapted to register with the longitudinal groove 51 and to move through the groove. The horizontal arm is provided with a radial arm 6!, having a lateral extension 6|, adapted to be shifted to a position close to the top of the flange 28, but slightly spaced therefrom, and in the path of travel of the traveler. The arm 59 is provided with a stop 62, to limit its outward move ment. A compressible coil spring 63 surrounds the arm 59 and engages the outer end of the bearing sleeve 55 and a head 64 is secured to the arm 59. When the radial arm El is swung to and out of horizontal position, the radial pin 60 engages the vertical shoulder 58' and the pin will register with the groove 5 and when the arm 6| is released, the spring 63 snaps the arm 6| to the outer position, so that this arm and its extension is out of the path of travel of the traveler and the balloon. When it is desired to stop the movement of the traveler, the radial arm 6| is first shifted inwardly toward the ring until the pin 60 moves out of the slot 5?. The radial arm is then swung downwardly to a vertical position at which time the pin 68 will engage the horizontal shoulder 59, and be out of alignment with the slot 51, and be held against outward movement by the closed end of the recess 55'. When the arm 6! is then released, it will remain in the vertical position and its lower end and extension 6| will be positioned above and near the flange 28 of the ring, in the path of travel of the traveler. The traveler will therefore be stopped and the bobbin and broken yarn manipulated for threading the broken yarn into the traveler and securing the broken yarn to the source of yarn, as explained in connection with the first form of the invention. All other parts of the apparatus remain identical as described in connection with the first form of the invention.

It is to be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
